TO ALL W HOM IT MAY CONCERN:

Be it known that I, C. H. HALL,-of Binghamton. in the county of Broome, and Stateof New York, have invented a new and useful improvement in Spring Bed-Bottoms; and I'do hereby declare that the following is a full, clear, and' exact description thereof, which will enable those skilledin the art to make and use the same, reference vbeing had to the accompanying drawing, forming part of this specification, in which drawing- Figure 1 is an elevation of a cross-section of a bedstead to which myA improvement has been applied,

lshowing the inner side of one end ofthe bedstead. I

' Figure 2 is an under side view ofthe bed-bottom and bcdstead.

Similar letters of reference indicate corresponding parts.

This invention relates to spring bedsbottoms, and consists, in general terms, in supporting the slats upon springs or elastic supports independently of each other, and in such a way, that when the slats are depressed by any weight, as when a person is lying thereon, the springs are woiind up to a certain extent upon the slats and upon the studs or pins that hold the springs, so that the springs are in fact shortened by the depression of the slats. The letters B B, &c., designate the slats of the bed-bottom. Their ends are rounded in order to receive the coils C of the springsvhich are placed upon said ends,` as shown in the drawing. The springsin' this example are composed of a strand or strands of round wire, but they may be composed of flat wire or 'of metallic plates or strips of the proper length, so that the same, when wound, canbe--placed upon said slats and upon the intermediate supports D, in continuation or in several sections from one side to the other of the bedhottom, or from the head to the foot thereof in cases where the slats are arranged transversely. In arranging and'securing the springs C, I employ pins D, which may for convenience sake consist of screws, whose heads prevent the coils of the springs from running or slipping o` such pins. Thcsepins I secure in the inside of the rails A, intermediate of and a little lower than the plane the slats are to occupy when the latter are not depressed. The ends of the springs or wire can be securedto the outermost slats in any way convenient tothe maker, or to the outermost pins of the series. The manner of winding or ceiling the spring or wire is shown Ymost clearly in tlg. 1, where it is seen that it is brought to the slats yon their under sides or from below, and to the pins on their upper sides or from above, or vice versa, the object of which is to cause the spring or wire to be forced against both the slatsA and the pins vand to be more and more coiled upon them and consequently shortened whenever the slats are depressed by tbe weight of the person who lies on them. The slats B are supported, as before described, at each of their ends,` whether they 'are arranged lengthwise of the bed-bottom or crosswise thereof. The vpins D may, if desired, be secured to a separate frame or to a strip, which may be afterwards attached or connected to the rails A of the bedstead, or they may be secured directly to the rails. The springs and the pins D, and the ends of the slats about which the springs are coiled, are covered and protected from direct contact with the mattress or bedding by means of inner rails E E, that project far enough from the inner sides of the rails A to accomplish this object. The springs or wiresare free to contract or expand upon the pins and upon the endsl of tbeslats. It results from this construction that the slats lare each independent of theothers, and are free to rotate in the coils of the springsgbut they are kept in a flat or horil zontal position by means of the mattress or bedding stretched or lying upon them, so that it is not necessary torfasten them to the coilsof the springs in any other way than by coiling the spring or wircvloosely or freely about their rounded ends. The wire or other elastic material of which the springs C are made extends in an unbroken length along the whole series of slats, or said springs may be made in several sections, if desired.

What claim as new, and desire to secure by Letters Patent, isf- The arrangement of a series of springs C, ea:ch hating three or more coi and on thepends of slats B, substantially in the manner and for thepurpo'se shown and described.
